I have two desktops and a single laptop connected up to three M26C cameras in the mini-WASP observatory. I fired up Tom How’s synchronisation program to make sure it can control 3 cameras o.k. – it did of course. Next test was to see if I could take LONG exposures with cameras 1 & 2 (as if I was taking narrowband data) whilst taking multiple short exposures with camera 3 – the dithering is linked to camera 1. This worked fine too, so I can take multiple RGB exposures with the TS 80mm triplet APO whilst taking a single narrowband image of the same region with the 2 Sky 90s. How cool is that?
